Description

The invention relates to a ski binding, such as a pure alpine binding or a combined downhill and touring binding, with a toe holder for holding a front end of a ski boot, a heel holder for holding a rear end of a ski boot and a ski brake that is positioned between the toe holder and the heel holder is arranged. The ski brake can be moved back and forth between a first position, in which it does not develop a braking function, and a second position, in which it can brake the ski, and by means of a securing element for the ski brake in the first position, for example for transport or touring must be secured.

From the US 2014/0159343 A1 a ski binding with a brake and a securing element for the brake is known. The securing element is a slide which is linearly displaceable along a longitudinal axis of the ski brake from a release position for the ski brake into a locking position for the ski brake. The securing element comprises an operating end which protrudes at the end of the heel holder facing away from the toe holder and can be displaced from the release position into the locking position and back by means of a ski pole. The DE 29 19 480 A1 shows a U-shaped securing element for the brake of a ski binding.

It is an object of the invention to provide a ski binding with a ski brake with a securing device for the ski brake that is simple and inexpensive to manufacture, the securing device being easy to operate and reliably holding the ski brake in the secured position.

This object is achieved by the subject matter with the features of claim 1.

One aspect of the invention relates to a ski binding, such as an alpine or downhill binding or combined downhill and touring binding, with a toe holder for holding a front end of a ski boot, a heel holder for holding a rear end of a ski boot, a ski brake that is between the toe holder and arranged on the heel holder and can be moved back and forth between a first position in which the ski brake does not develop a braking function and a second position in which the ski brake can brake a ski. In the first position, for example, the tentacles of the ski brake in the Be oriented essentially parallel to the ski and rest on the ski, while the tentacles are pressed into the snow in the second position and can thereby brake the ski, in particular the ski that has been detached from the ski boot. The heel holder comprises a base via which the heel holder is or can be connected to the ski.

The ski brake includes a securing element with which the ski brake can be secured in a locking position, for example for transport or touring, so that the tentacles of the ski brake still rest on the ski and cannot develop a braking function even when the ski boot is lifted from the heel holder. The securing element is a slide that moves in the longitudinal direction of the ski from a release position, i.e. a position in which the ski brake is not fixed in the locking position on the ski and the ski brake is adjustable into the second position when the ski boot is lifted off the ski, into the locking position for the ski brake is preferably linearly displaceable, and vice versa.

The slide can in particular be formed from a preferably rigid wire, a tube, a sheet metal or another profile. The material for the slide can comprise a metal, in particular a light metal such as aluminum, and / or a plastic. The slide can be manufactured in one piece or composed of several parts, wherein the different parts can be formed from different materials or can comprise different materials. The slide can in particular be bow-shaped or have the shape of a flat plate with or without recesses.

The slide comprises an operating end which protrudes at an end of the heel holder facing away from the toe holder or laterally on one side, preferably an outer side, or both sides / outer sides of the heel holder. A protrusion is understood here in particular as a protrusion that allows the slide to be grasped by hand or, for example, with the tip of a ski pole. The operator can protrude parallel to a ski surface and / or be bent upwards away from the ski surface towards the ski boot at any desired angle. The operator can include an opening for engagement for the ski boot tip or be shaped so that it can be easily grasped by hand or with the tip of the ski pole. The operator can also protrude using a separate component. This can be done on the toe holder remote end of the ten holder or laterally on one side, preferably one outside, or on both sides / outside of the heel holder, at least one control element can be provided which is shaped so that it can be easily gripped by hand or with the tip of the ski pole. The operating element is preferably formed from a textile so that it is easy for the user to grasp and also has only a low weight. Furthermore, the textile can be a Velcro tape, which can be looped around the operator in a simple manner and can be easily attached using the Velcro fastener. "By hand" in particular has the meaning of "without using a tool", that is, the operator or the operating element can be gripped with the fingers of the hand and the slide can thus be moved into the locking position and into the release position. It is conceivable, even if less preferred, since it would increase the number of components and the complexity of the locking, that the movement of the slide into and / or out of the locking and / or release position is supported by a spring element in order to avoid that the slide remains in an intermediate position between the locking and release position.

The slide further comprises a locking end which, to lock the ski brake, engages in a locking counter-element which is arranged on the ski brake, that is, firmly connected to the ski brake or, for example, is formed in one piece with a pedal of the ski brake. The locking of the ski brake in the first position, i.e. in the position in which the ski brake does not develop a braking function, for example for transport or touring, takes place in that the securing element is shifted into the locking position, i.e. forwards as seen in the longitudinal direction of the ski . The ski brake, which is currently still in the second position, is then depressed into the first position by stepping on the pedal with a ski boot, where the locking ends of the securing element can engage with the counter-locking element and the ski brake is thus fixed in the first position. If the securing element is in the release position, the ski brake can first be depressed from the second position into the first position, for example by stepping on the pedal with the ski boot or by manually depressing the pedal. The securing element can then be moved from the release position into the locking position, that is to say forwards as seen in the longitudinal direction of the ski. The locking ends of the securing element can now with the Locking counter element come into engagement and the ski brake can thus be set in the first position.

The slide can be fixed at least in the locking position, so that an unintentional release of the slide from the locking position is prevented. The same applies to the release position for the ski brake, in which the slide can also be fixed in order to prevent unintentional movement of the slide from the release position into the locking position, for example.

The slide can have at least one arm which is connected to the operating end and which has a free end at the securing end. At least one arm means that the slider can have a single arm, two arms, three arms, or more arms. If the slider has more than one arm, each of the arms is preferably connected to the operator and the arms can run parallel to one another and have the same or different lengths. The shape and / or diameter and / or material etc. of each individual arm can also be the same or different from that of another arm if the slide comprises more than one arm.

The slide can in particular be guided preferably linearly below the heel holder, for example in the base for the heel holder, or in a lower housing part of the heel holder facing the ski surface or the base. For this purpose, the shape of the slide or of the at least one arm of the slide can be adapted to the structural conditions in the base or in the lower housing part of the heel holder. That is, the slider or the at least one arm of the slider can be shaped and designed in terms of its dimensions so that it does not come into conflict with other parts for the heel holder that are arranged in the base and / or in the lower housing part, such as for example a thrust spring, adjusting screw, etc.

To enable the slide to be secured in the locking position and / or in the release position for the ski brake, the slide or the at least one arm of the slide can have a latching element that is used to secure the slide in the locking position in a first counter-latching element and / or to secure the Slider engages in a second counter-locking element. If the slide comprises more than one arm, it can be sufficient if only one of the two or more arms has the latching element. The first counter-locking element and / or the second counter-locking element can in particular be formed in the base for the heel holder or in the lower housing part of the heel holder. The first and the second counter-locking element can be separated from one another by an elevation. A maximum displacement path of the slide can be predetermined by the two locking positions of the locking element in the first counter-locking element and the second counter-locking element.

The locking element of the slide or of the at least one arm of the slide can be an additional part that is connected to the slide / the at least one arm of the slide, or it can be formed by a regional deformation of the slide / of the at least one arm of the slide. In order to move the locking element out of the first or the second counter-locking element, the slide / the at least one arm of the slide can be pushed elastically transversely to the central longitudinal axis of the ski brake, for example in the direction of a central longitudinal axis. As a result, the locking element is biased in the opposite direction and can lock into the respective counter-locking element when the first or the second counter-locking element is reached.

The counter-locking element can be plate-shaped, with at least one opening into which the locking end of the slide engages in the locking position of the ski brake in order to secure the ski brake against being triggered. The at least one opening can open into at least one wall, preferably a side wall of the counter-locking element, which is directed essentially perpendicular to a ski surface, with an opening cross-section that is at least as large as a diameter of the locking end of the slide or of the at least one arm of the slide. The at least one wall of the counter-locking element below the at least one opening can have a slope which, when the ski brake pedal is depressed, elastically deflects the locking end of the slide or the locking end of the at least one arm of the slide. The slope can be designed in such a way that it moves the at least one arm or the locking end of the slide in at least one transverse direction, which is a direction that is essentially perpendicular to a central longitudinal axis of the ski brake in a plane that is essentially parallel to a ski surface. In an embodiment of the invention with two arms, the arms are moved in opposite transverse directions, as a result of which a distance between the two arms increases, for example. The locking end of the slider or the locking end of the at least one arm of the slide can elastically snap into the opening after overcoming the incline. In an embodiment with two arms, this reduces the distance between the arms again. However, it is also conceivable that the two arms are moved in transverse directions that are aligned with one another, whereby a distance between the two arms is reduced. Here, too, the locking end of the slide or the locking end of the at least one arm of the slide can elastically snap into the opening after overcoming the incline, whereby the distance between the arms increases again.

The counter-locking element can be formed from a metal, for example steel or aluminum, or from a plastic, or comprise a metal and / or plastic. For example, the body of the counter-locking element can be formed from a plastic that is surrounded, for example, on one, two or three sides or circumferentially with a metal frame that forms or at least lines the bevel and the opening. This solution can advantageously lead to a reduced weight of the ski brake, but on the other hand it can increase the manufacturing effort, which can lead to an increase in the cost of the ski brake.

In order to change from the downhill position to the touring position and to enable the binding to be released from the side in downhill mode, the heel holder can be pivoted about an axis perpendicular to a ski surface in a swivel joint. The slide or the at least one arm of the slide can in particular run below the rotary joint and / or to the side of the rotary joint.

The slide can have identical cross-sectional areas throughout or different cross-sectional areas in certain areas. It can consist of a single part or be composed of several parts that are preferably non-detachably connected or connectable to one another.

In the base or in the lower housing part of the heel holder, a guide channel for a portion of the slide or the at least one arm of the slide can be formed, which guide channel closely guides the slide / the at least one arm of the slide. This means that the dimensions or internal dimensions, such as the height and width of the channel, essentially correspond to the dimensions or external dimensions of the slide / of the at least one arm of the slide.

The ski brake can be constructed as a separate unit in relation to the heel holder and attached to the ski with additional fastening elements via a base. The base of the ski brake can additionally have at least one cover which covers the components of the ski brake arranged between the base and the cover and thus prevents snow, ice and / or dirt accumulation in this area. The at least one cover preferably has no opening in the cover area, but rather forms a closed surface. At least one upper side of the cover facing the ski boot can have a smooth or very finely structured surface. The material for the cover is in particular selected so that it advantageously has water, snow, ice and / or dirt-repellent properties, or at least has a coating with the properties mentioned on the upper side facing the ski boot. The surface of the cover can be printable. The at least one cover can also be produced in one piece as a separate part from the base of the ski brake, for example from a thermoplastic such as PA6. The ski brake and the heel holder can each include a base, and the base of the ski brake and the base of the heel holder can overlap in areas when the binding is mounted on the ski. The overlap area of the base of the ski brake can be arranged between the ski surface and the underside of the overlap area of the base of the heel holder, or vice versa. Fastening elements for attaching the binding to the ski can simultaneously reach through the base of the ski brake and the base of the heel holder and thereby connect both parts to the ski and to each other in such a way that a relative movement of the ski brake base to the heel holder base is excluded.

The invention thus comprises a ski brake with a base with which the ski brake can be connected to a ski and / or a heel holder, a pedal with a contact surface for a ski boot, a spring device that biases the pedal in a first direction, in the one plane the contact surface of the pedal has a maximum distance from a ski surface when the ski binding is connected to a ski, at least one tentacle arm that is connected to the pedal, and a securing element for securing the pedal in a locking position in which the plane of the contact surface of the Pedals has a minimal distance from the ski surface when the ski binding is connected to a ski. The securing element is in a bearing element that is connected to the base or through the base is formed, held and guided displaceably in a first longitudinal direction and in a second longitudinal direction which is opposite to the first longitudinal direction.

The catch arms engage with a respective arm section via corresponding openings on the underside of the pedal in a coupling element. The coupling element is inserted into an opening on the underside of the pedal, it being possible for the opening to be designed to be open in the direction of the ski surface. The coupling element is preferably designed in the form of a hollow cylinder, so that it provides a receiving opening for the respective arm section at both ends. However, any other shape of the coupling element is also conceivable which also provides at least one corresponding opening for engaging the respective arm section. The openings which are formed on the underside of the pedal for receiving the arm sections are oriented in accordance with the at least one opening on the coupling element. The size of the at least one receiving opening in the coupling element is designed such that the respective arm section sits tightly in the receiving opening. This means that the dimensions or internal dimensions of the respective receiving opening essentially correspond to the dimensions or external dimensions of the respective arm section of the tentacle arm.

The height of the coupling element can be dimensioned such that it protrudes in the direction of the ski surface with respect to a base surface of the pedal. The protrusion of the coupling element can enable the pedal to stop on the ski surface when stepping on the pedal, e.g. when stepping into the binding or when walking with the binding in a touring position at a zero height. On the one hand, this can serve to limit the movement of the pedal in the direction of the ski surface. If a suitable material is selected for the coupling element, this can also serve to dampen the contact between the pedal and the ski surface, which also reduces the generation of noise.

The coupling element can be formed from an elastic plastic, for example silicone, or comprise such a plastic. The plastic preferably has dirt, ice, snow and / or water-repellent properties or a surface with these properties. A resilient plastic is particularly advantageous since the coupling element over the respective arm section engaging tentacles may not execute synchronous movements with one another when adjusting the brake in the different positions. The elasticity of the plastic material enables a certain different movement to one another, yet offers a certain coupling of the tentacles to one another and also achieves a certain damping of the movement.

The bearing element can be formed from an elastic plastic, for example silicone, or comprise such a plastic. The plastic preferably has dirt, ice, snow and / or water-repellent properties or a surface with these properties. An elastic plastic is particularly advantageous because the at least one arm mounted in the bearing element or the locking end of the slide, as explained above, must engage in a corresponding opening of the locking counter-element when the ski brake is locked and deflects itself elastically in at least one transverse direction. The elasticity of the plastic material enables and at the same time limits the path of this movement and also achieves a certain damping of the movement. The spring device preferably consists of a single spring element with two spaced apart spring sub-elements which are arranged parallel to one another and which are inseparably connected to one another or which are originally formed in one piece. The spring device can be pushed onto an axle so that a connecting section of the spring device connecting the first spring sub-element and the second spring sub-element protrudes from the axle in the longitudinal direction of the ski in the direction of the toe holder and the two spring sub-elements are mounted on the axle. Less preferably, the spring device can comprise a first spring element and a second spring element, which are arranged on the axis at a distance from one another. The securing element can extend below the axis and between mutually facing ends of the spring device. The axle is preferably mounted in the base of the ski brake. The axle can further secure the cover of the base in place by providing corresponding receiving openings in the cover through which the axle extends.

The invention consequently relates to a ski binding with a heel holder with a base, at least one sole holder and a housing, wherein in the base and / or in a lower housing part of the heel holder facing the base at least one counter-locking element for a locking element of a securing element for a Include ski brake and / or at least one guide channel for part of the securing element for the ski brake.

An exemplary embodiment of the invention is explained in more detail below with reference to figures. Features essential to the invention, which can only be inferred from the figures, belong to the scope of the disclosure and can advantageously develop the subject matter of the invention individually and in the combinations of features shown.

The Figure 1 shows an exploded view of an embodiment of a ski brake 10. Only the most important parts of the ski brake 10 are provided with reference symbols and named in the description of the figures.

The ski brake 10 comprises a base 11, a pedal 12 with a contact surface 13 which can be or is connected to the pedal 12, a spring device 14 and a first catch arm 15 and a second catch arm 16. Each of the catch arms 15, 16 comprises a paddle 19. An arm section 15a and an arm section 16a of the first tentacle arm 15 or of the second tentacle arm 16 are guided in corresponding openings in the pedal 12 and engage in a coupling element 40. In the exemplary embodiment shown, the coupling element 40 has the profile of a hollow cylinder, the engagement of the arm sections 15a, 16a taking place at a respective end of the hollow cylinder. For receiving the coupling element 40, the pedal 12 has an opening 12a which is designed to be open towards a base surface 12b of the pedal 12 (see FIG Figures 8 and 9 ). The ski brake 10 furthermore comprises an axle 18 on which the spring device 14 can be mounted, and a bearing element 17 which can be connected to the base 11. The ski brake also comprises a cover 32 which is placed on the base 11 and additionally secured via the axle 18.

The ski brake 10 further comprises a securing element 20 in the form of a slide 20, which in the exemplary embodiment comprises an operating end 21 and two arms 25, 26 each with a locking end 22, 23. A separate operating element 30 in the form of a Velcro strip 30 is attached to the operating end 21, which supports an adjustment of the slide 20 in at least one adjustment direction. One of the arms 25 has a deformation near the operating end 21, which forms a latching element 27 with which the slide 20, for example, in an in Figure 8 shown base 31 of a heel holder can be held in one or more predetermined positions. The function of the locking element 27 is shown in the description of the figures Figure 8 explained in more detail. Finally, the ski brake 10 comprises a counter-locking element 24 which can be connected to an underside of the pedal 12. The locking counter element 24 can with the locking end 22, 23 of the slide 20 cooperate to hold the ski brake in a locking position in which it cannot be released.

The slide 20 of the exemplary embodiment is made from a wire or a tubular profile in one piece, for example by cold or hot deformation. The operator 21 protrudes vertically from the arms 25, 26 upwards. A Velcro tape 30 is attached to the operating end 21, the two ends of which are looped around the cross section of the operating end 21 and engaged with one another. The Velcro tape 30 and / or the operator 21 can be moved, for example, by hand without the use of a tool in the direction of the pedal 12 to lock the ski brake 10 on the ski, not shown, and in the opposite direction to unlock the ski brake 10.

The Figure 2 shows the ski brake of the Figure 1 assembled in a perspective view from above. Not shown in Figure 2 the cover 32 and the Velcro strip 30. The Figure 2 shows the ski brake 10 in a second position in which it can brake the ski. The slide 20 is in the foremost position in which it would lock the ski brake 10 if the pedal 12 were depressed on the base 11. The locking ends 22, 23 of the arms 25, 26 reach through the bearing element 17, which is formed, for example, from an elastic plastic such as silicone. The spring device 14 comprises a first partial spring element 14a, a second partial spring element 14b and a connecting section in the form of a U-bracket 14c, which connects the first partial spring element 14a and the second partial spring element 14b, both of which are mounted on the axis 18. The U-bracket 14c extends in the longitudinal direction L of the ski in the direction of a toe holder (not shown) and is pivotably connected to the pedal 12 of the ski brake. The slide 20, respectively the arms 25, 26 of the slide 20, have a shape which is selected such that the slide 20 can be passed through between the opposite ends 14a1, 14b1 of the spring sub-elements 14a, 14b.

The Figure 3 shows the ski brake of the Figure 2 in another perspective side view. The spring device 14 biases the pedal 12 in a first direction in which a plane of the contact surface 13 of the pedal 12 is at a maximum distance from a ski surface when the ski binding is connected to the ski. The pedal 12 and the arms 15, 16 with the paddle 19 are in opposite directions Direction pushed away from the base 11. The bearing element 17 forms a front end of the base 11, the bearing element 17, as in FIG Figure 1 It can be seen that it is placed on the front end of the base 11 or on the holders 11a, 11b formed there for the bearing element 17 and secured to the base 11 by a form and / or force fit, possibly supported by a cohesive connection such as adhesive . The bearing element 17 can alternatively also be connected to a front or rear side of the mountings 11a, 11b, for example glued over the entire surface. The mountings 11a, 11b of the exemplary embodiment have slots 11a1, 11b1 which are open towards the respective outside (see FIG Figure 1 ) which, like a synopsis of the Figures 1 and 2 suggests that the locking ends 22, 23 of the slide 20 are also penetrated. The slots 11a1, 11b1 form a guide for the locking ends 22, 23 or the slide 20 or the arms 25, 26 in the base 11 of the ski brake 10 and allow the locking ends 22, 23 to be pushed apart against the elastic force of the bearing element 17 , but cannot be moved up or down, or pressed towards each other.

The Figure 4 shows the ski brake of the Figure 2 in a perspective view from behind. In the figure, the counter-locking element 24 can be clearly seen for the first time, which is connected to an underside of the pedal 12 via a bolt 33. In the embodiment, the U-bracket 14c overlaps (see Figure 1 ) of the spring device 14 the bolt 33, so that a spring force of the spring device 14 can act on the pedal 12. The catch arms 15, 16 with their respective arm sections 15a, 16a also engage the pedal 12 via corresponding openings, so that when the pedal 12 is depressed on the base 11, the catch arms 15, 16 are pivoted upwards against the spring force and next to the base 11 come to rest.

The counter-locking element 24, similar to the holders 11a, 11b, has slot-shaped openings 28, 29 which are open to the respective side wall 24a, 24b pointing away from the central longitudinal axis L of the ski brake 10. The slot-shaped openings 28, 29 have a mouth or opening width that allows the locking ends 22, 23 of the slide 20 to be moved into the openings 28, 29 from the respective side. Below the openings 28, 29, the side walls 24a, 24b have inclined surfaces 24a1, 24b1 which run from the respective side wall 24a, 24b in the direction of the central longitudinal axis L.

If the pedal 12 is now moved down when getting into the ski binding, the catch arms 15, 16 are simultaneously moved up in the opposite direction. When the pedal 12 is moved downward, the inclined surfaces 24a1, 24b1 of the counter-locking element 24 come into contact with the locking ends 22, 23 and push them apart, that is, increase a distance between the two locking ends 22, 23 in at least one respective transverse direction Q1, Q2 (shown in Figure 7 ), which runs perpendicular to the central longitudinal axis L of the ski brake 10 in a plane which is parallel to a ski surface. The bearing element 17 is also stretched to a lesser extent, as a result of which the bearing element 17 receives a preload which acts against the direction of movement imposed on the locking ends 22, 23 by the inclined surfaces 24a1, 24b1 of the counter-locking element 24. If the pedal 12 is moved further down, the locking ends 22, 23 come into the area of the mouths of the slot-shaped openings 28, 29 in the mating connection element 24 and can be moved into the openings 28, 29 due to the forced elastic pretensioning of the bearing element 17. The ski brake 10 is now locked.

To lock the ski brake 10, the pedal 12 can alternatively be pressed by hand onto the base 11 and then the slide 20 manually from a release position for the ski brake 10 into the locking position for the ski brake 10, as shown in FIG Figures 2 to 4 show where the locking ends 22, 23 are in engagement with the counter-locking element 24. In the case described above, the slide 20 is pushed into the locking position by hand without the locking ends 22, 23 coming into engagement with the counter-locking element 24. The engagement is first established by depressing the pedal 12, as described in the previous paragraph.

The Figure 5 shows the locked ski brake 10 in a sectional view through the central longitudinal axis of the locking end 22, in a plane parallel to a plane that includes the central longitudinal axis L of the ski brake 10. The locking end 22 extends through the bearing element 17 and the counter-locking element 24, so that the spring device 14 can no longer push the pedal 12 and the catch arm 16 apart, even when the pedal is relieved, such as during transport or touring. The slide 20 and thus the operating end 21 of the slide 20 is relative to the base 11 of the ski brake 10 in its foremost position, that is, the locking position.

The Figure 6 shows the same view as that Figure 5 except that here the operating end 21 of the slide 20 is in the release position, that is to say further away from the base 11 of the ski brake 10. The locking end 22 still passes through the bearing element 17 but no longer the counter-locking element 24, so that when the pedal 12 is relieved, the spring device 14 can move the pedal 12 upwards and the catch arm downwards away from the base 11. The ski brake 10 is now in an unlocked state and can, for example, develop its braking effect in the event of a fall on a descent, in which the ski boot is lifted off the pedal 12, in that the paddles 19 engage the ground.

The Figure 7 shows the ski brake 10 in a front view in one Figure 5 defined section, in the first position with a load that acts on the pedal 12. For locking the ski brake 10, the locking ends 22, 23 of the slide 20 are arranged in the openings 28, 29 of the counter-locking element 24 above the slopes 24a1, 24b1. During the locking, as already explained, the two locking ends 22, 23 are moved in at least one respective transverse direction Q1, Q2. The counter-locking element 24 is connected to the pedal 12 via the bolt 33, which in turn is connected to the tentacle arms 15, 16 via the spring device 14 in such a way that a movement of the pedal 12 perpendicular to the base 11 always causes a movement of the tentacle arms 15, 16.

The Figure 8 FIG. 10 shows a perspective view of the assembled ski brake 10 of FIG Figure 1 from below with lifted cover 32, spring device 14 and axis 18. The slide 20 with the operating element 30 is pushed into the base 11, the locking ends 22, 23 of the slide 20 engage in the locking element 24, so that the pedal 12 on the ski would rest, the paddles 19 are in the position in which the ski can be used for touring.

In this figure it becomes clear that the axle 18 not only forms a receptacle and a bearing for the spring sub-elements 14a, 14b of the spring device 14, but at the same time connects the cover 32 to the base 11 in a captive manner so that the spring device 14 arranged below the cover 32 cannot get dirty easily. Here, the axle 18 passes through a correspondingly designed opening in the cover 32, the axle 18 simultaneously reaching through at least one opening 39 in the base 11 in the assembled state of the ski brake

The Figure 9 shows the assembled ski brake 10 in a view from below Figure 1 shown from below with a base 31 for a heel holder. The slide 20 is guided in a guide channel 38 in the base 31 and has, near its operating end 21, the latching element 27, which can engage in a counter-latching element 34, 35 formed in the base 31, in order to lock the slide 20 in the two through the counter-latching elements 34 To secure 35 against unintentional displacement along the central longitudinal axis L. In the Figure 9 the slide 20 is locked in the position in the counter-locking element 35 for the release position, that is, in the position in which the ski brake 10 is not locked, the ski can consequently be used for a descent. When the slider 20 is moved by the user from the release position into the locking position in which the ski brake 10 rests on the ski even in the unloaded state, the latching element 27 engages in the counter-latching element 34. The two counter-locking elements 34, 35 are arranged directly next to one another in the exemplary embodiment and are only separated by a web 36. The web 36 is designed so that the locking element 27 cannot rest on the web in a stable position, but rather has the tendency to slide into the counter-engaging element 34 or the counter-locking element 35 in the direction of the central longitudinal axis L even with the slightest force.

Reliable latching is made possible by the fact that the slide 20, or the arms 25, 26 of the slide 20, can be pressed elastically towards one another when moving along the central longitudinal axis L in the area between the operator 21 and the latching element 27, whereby the slide 20 is biased in this area. When the latching element 27 has then overcome an apex 37 of the web 36, the latching element 27 is pressed into the counter-latching element 34, 35 by this pretensioning force.

The Figures 8 and 9 furthermore show an opening 12a in the pedal 12 in the direction of a ski surface, in which the coupling element 40 rests. The arm sections 15a, 16a engage in the corresponding openings of the hollow cylindrical coupling element 40. The coupling element 40 is like this dimensioned that it, as in Figure 8 to recognize, with respect to the base surface 12b of the pedal 12 protrudes in the direction of the ski surface.
